Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604434, here are decompositions:

47 + 31604387 = 31604434
131 + 31604303 = 31604434
137 + 31604297 = 31604434
383 + 31604051 = 31604434
401 + 31604033 = 31604434
443 + 31603991 = 31604434
503 + 31603931 = 31604434
557 + 31603877 = 31604434

Showing the first eight; more decompositions exist.
